First off, it would be a controlled, slow descent, so a large part of Phobos' fall would warm up the atmosphere as it trails burning overhead. When it crashes into the Martian North Pole, it will send debris flying into space. However, Martian gravity is strong enough to reclaim almost all the ejection, and it will rain down across the planet, burning in the thin Martian atmosphere. Two things will happen:
1) As the iron oxide and chunks of water and CO2 ice rain down on Mars, it will raise the air pressure a substantial amount, causing Mars to be able to retain much more heat.
2) Because of this, seas and lakes will form in the equatorial regions.

The idea that Phobos smacking will cause a net drop in temperature is absurd. The amount of heat it will produce will outweigh the half a year or so of a planetary dust storm. After it is all done, Mars will now have a partial Earth-pressure CO2 and Oxygen atmosphere with liquid water on the surface. 50% of the job done right there.
